BacksertExtensionBacksertT Method
            Inserts the elements of a sequence into another sequence at a
            specified index from the tail of the sequence, where zero always
            represents the last position, one represents the second-last
            element, two represents the third-last element and so on.

IEnumerableT
            A sequence that contains the elements of 
first
            plus the elements of 
second inserted at
            the given index from the end of 
first.
            In Visual Basic and C#, you can call this method as an instance method on any object of type 
IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see 
Extension Methods (Visual Basic) or 
Extension Methods (C# Programming Guide).
 
            This method uses deferred execution and streams its results.
